TIRE covRR.,-

Application tiled December 4, 1922. Serial No. 604,952.

To all whom it may concern: v

Be it known that I, MARTIN B. LoET- soHnR, a citizen of the United States, and a resident of Hollywood, countyI of Los Angeles, State of California, have invented a new and useful Tire Cover, of which the following isa specication.

The present invention relates to improvements in tire covers and its particular object is to providea cover for a tire secured to a rim that can'be very easily and quickly fastened to the tire so as to completely surround and protect the same. Two principal forms of my device arev described lin the specification, one being made in one piecet and adapted to be sprung on the tire, and the other beingmade of two halves adapted to be placed on the tire from opposite sides and to be engaged with one another through spring action in combination with a certain means for fastening one of the halves. rllhe latter form may be modified to cover, 9none side, the entire area enclosed by the rim.

rIhe preferred forms of my invention are shown in the accompanying drawing in which Figure 1 represents a side lview of a tire having my cover thereon, Figure 2 a sectional detail view explaining a spring lock (mechanism, Figure 3 a plan Jview of vsaid mechanism, Figure 4 a cross section through the tire with the cover secured thereto along a radial line, Figure 5 a cross section through a modified form of the tire cover, covering the whole area enclosed bythe rim, Figure 6 a modified form of tire cover in side elevation, and Figure 7a cross-section through the same taken along any radial line. While I have shown only the preferred form ofthe invention it should be understood that various changes or modifi cations mayy be`made within the scope of- "the claims hereto attached without departing from the s irit of the invention.

The tire (1)) which may be of any suitable construction and form is secured on the p tire rim (2) in any suitable manner as for instance bythe engagement of the beads (3) with the flanges (4) of the rim. My cover,

`the tire it is made for. Its'inner margin (8) is turnedupon itself as shown at (9) and adapted to be forced lbeinrveen the tire and the ange of the tire rim in the manner shown in Figure 4. The outer margin (11) of the section (6) is ange'd and crimped inf to substantially circular form, the flange being disposed substantially in the central vertical plane of the tire.

The second section (7) is formed to complement the section (e6), its inner being flanged in the same manner as shown at (12) and its outer margin being iangedv and curved to Ht around the crimped flange of section (6) with a short projection (13) extending beyond the latter. Bothsections are split transversely as shown at (14) with the two ends overlapping when the cover is in place. The two ends of section (7) are argin l secured to one another by means ofthe lockv l shown in Figures 2 and?) comprising a ratchet (16) secured to one of the ends and the spring member (17) secured to theother end and provided with vratchet teeth (18) adaptedto engage the. ratchet before meni tioned. A bent portion (19) forms the end of the spring (17) and allows of easy manipulation of the same. v

To place the cover on the tire the sectionV second section is thenplaced on the other l side and the outer flange of the same sprung on the crimped flange of the first sectlon .which operation is made 1possiblethrough the fact that the second section is split as at (14). After the second section has been placed in its proper position the two'ends of the same are forced over one another as far as canconveniently be done and the` ratchet arrangement vshown in Figure 2 will automatically lock the whole cover.

The form thus far described may be slightly modified as shown in Figure 5, in which one section is made solid to cover the whole area of the tire as shown at v(21),

the engagement' of thev inner margin between the tire and the tire rim being eliminated.

form in which the whole tire cover -(21) is made -of a single unit. The peripheral .y joint is omitted while the inner margin (22) In Figures 6 and 7 is shown a modified is turned upon itself in the manner prel viously' described. The cover is split transversely as shown at (23), one end overlapping the other. The locking deviceis side of the tire terminating in a crimped flange surrounding the tire peripherally, a second element adapted to engage the other Side of the tire being split transversely and terminating in a flange adapted to be sprung over the crimped flange for firmly engaging the same, and means for locking the tire at the split comprising ratchet teeth associated with one end of the second element7 and a Y spring member associated with the other end havingrratchet teeth adapted to engage the former teeth.

2. A cover for a flanged tire rim having a tire supported between its flanges comprising a ring curved transversely adapted to lie against one side of the tire with one edge clamped between the tire and a rim flange and the other edge terminating in a rounded flange surrounding the tire peripherally and asecond ring adapted to similarly yengage the other side of the tire being split transversely and terminating in a rounded flange adapted to be sprung over the first rounded flange for firmly engaging the same.

3. A cover for a flanged tire rim having a tire supported between its flanges comprising a ring curved transversely adapted to lie 'against one side of the tire with one edge clamped between the tire and a rim flange and the other edge terminating in a crimped flange surrounding the tire peripherally7 a second ring adapted to similarly engage the other side of the tire being split transversely and terminating in a flange adapted to be sprung over the crimped flange for firmly engaging the same, and means for locking the tire at the split, comprising ratchet teeth associated with one end of the second element, and a spring member associated with the other end having ratchet teeth adapted to engage the former teeth.

4. A cover for a tire mounted on a tire rim having retaining flanges thereon, comprising a casing made to conform to the outlines of the tire and split transversely so as to be adapted to be sprung on the same having its marginal edges turned upon itself to fit between the tire and the flanges of the rim, and means for locking the cover in its operative position comprising ratchet teeth vassociated .With one end of' the cover and a spring member associated with the other end having ratchet teeth adapted to engage the former teeth.
